triphand at zero whenever the key is inserted,

and means for instantaneously operating the hundreds-register at theproper moments.

The improvements which constitute the present invention relate primarilyto said parts of our original apparatus; but the improved devices areapplicable to other registers.

The obj ects of the first part of this invention are, first, to providefor the employment of a key of simple construction, and to insure therotation of this key in the proper direction, and its withdrawal whenthe trip-hand is set at zero, and to prevent its withdrawal until it hasmade a complete rotation; secondly, to give audible notice of theapproach of the trip-hand to zero when it is actuated by key,-

so as to prevent straining the zero-guard accidentally; thirdly, toprovide by superior means for inserting the key at any time,irrespective of the position of the trip-hand, and to prevent thewithdrawal'of the key after it is once engaged with the shaft of thetrip-hand gearing untilit is brought to zero fourthly, to prevent theevasion of detection by leaving the key in until thetrip-hand reacheszero by subsequent registrations. Any successful manipulation ofthe'trip-hand is thus prevented, and the detection of any attempt toaccomplish such manipulation is insured, with the aid in all cases ofthe permanent register.

The objects of the second part of the invention are to facilitateadjusting the trip-hand with reference to the resetting mechanism inassembling the parts in the original manufacture and after repairs, andto keep the gearing of this mechanism in perfect mesh. very amplefrictional connection of these par ts with the ,main shaft is at thesame time secured in the most simple manner. A

The object of the third part of the invention is to;render the mechanismof-thehundreds-register more strong, simple, and effeetive. I 1

This improved passenger-register has a circular inclosing-case,consisting of a sheetmetal drum, z, and a glass face-cover, 3 andattached by screws 01: to the back-plate w of the registering mechanism;Parallel to the face a dial-plate, d, is supported, and this is piercedwith orifices o o for a pair of shafts, A B, which carry index-hands H Hand with an index-orifice, 0 Unit-dials d 9?, each of a capacity of 100,are marked on the dial-plate d, concentric with the orifices 0 0 and ahundreds-dial, ll, of twenty spaces, rotates besEsT AVAILABLE cos hindthe orilice oi. The first dial, a is concentrici'vfitli'the" case, andas large as it will accommodate, "and constitutes, with the hand ."Fig.2,'protected'internally by wire-gauze,

The ratchet-wheel B, through its shaft A, apinion, P, of the same number of teeth, thereon, and a pair ofspur-whee1s,'W W each having one hundred teeth, drives the shafts A B,and, consequently,'the index-hands H H synchronously, said spur-wheels WW being keyed on said shafts A 13. A detent-pawl, X, having a tail-spring, s, prevents any backward movement of the train and a skeletonyoke-frame or spider, 8,

attached to the back-plate to, forms therewith the requisite supportsand guides for the parts. By this'mechanism each fare issimultaneousl'y'registered on the two dials (Z (P, and an alarm issubsequently sounded to attest the registration. The movements of theslide S are indicated by arrows l 2. Those transmitted by the feed-pawland hammer F are indicated by arrows 3, and the striking motion of thelatter by-arrow 4.

The parts above described are the same as those correspondingly letteredin our Patent No. 190,021, hereinbefore referred to, except inunessential mechanical details.

For operating the hundreds-dial H a strong projection, 12, is securelyattached to the shaft B near its inner end. Once in each rotation of theshaftB this projection comes in contact with a projection, 12, at oneend of a slide, S and this slide carries a feedpawl, F having atail-spring, s by-which it is kept in mesh with a ratchet-wheel, R, on ashaft, 0, which shalt is that of said dial H said wheel R having onetooth for each of the spaces of said diaL- The slide S is guided byscrews 0 iii-passing through stop-slots in the slide into studs 10 a onthe back-plate; and the outer screw, 0 is provided with an extendedhead, of'hook shape, to which one end of a spiral spring,'s is attached.The other end of this spring is attached to a hook, it, at the inner endof the slide. The spring consequently tends to draw the slide outward,and is located in front of the slide and parallel thereto. The shaft 13,through the projections 17-12, draws the slide in the oppositedirection, as indicated by arrows 5, and holds it until the index-hand Hleaves 99 to register 100. A strong plate-spring, 5-, having adetent-rib,

. 'r, at its head, holds this detent-rib in mesh with a notchedcrown-flange, a, on the back of its supporting-studs a u.

The slide is also, in this connection, made yielding bymeans of a semielliptic spring, 8', interposed between it and In saidinward passes in contact with the back of the incline f, and said slideis forced back, soas to let said projection pass. When said slide isreleased by the projection 11 the spring 8 instantaneousl y draws saidslide outward, as indicated by arrows G; and in the first part of thismovement the projection g, passing in contact with the .face of theincline f, forces back the spring 8 and releases; the ratchetwheel R Theremainder of the motion shifts the dial-plate H one space through thepawl F ratchet-wheel R and shaft 0, and the latter is then relocked. byarrows 7. All this occurs in an instant.

The shaft 0 is a sleeve-shaft, mounted on a stud'shaft, G The former hasa broad flan go at its outer end to support the dial H and the innershaft has an undercut extremity, which engages with a key-hole slot inthe dial, and with the aid of a single screw securely attaches thelatter, while by the same means the sleeveshaft is held in place.

The index'hand H. is simply attached to the outer end of the shaft B bymeans of a ti ghtl yfitting cap. The trip-hand H is secured, by means ofa frictional hub, a, to the outer end of the hub of a bevelgear, b,which gear in turn embraces the outer end of the shaft A, so as to rotate therewith in the direction of the arrows 3, but so also as to becapable of independent rotation. Along sleeve-shaped hub, to isaccommodated, thus affording ample frictional surface. The independentfrictional attachment of the hand to the gear provides for adjusting thelatter irrespective of the mesh of the gear. A lateral set-screw, aentering a circumferential groove inthe shaft A, holds the gear I) inposition, so as to keep it in mesh with a similar gear, W, on the innerend of a radial shaft, D, which is supported parallel to the dial-plateby a supplemental frame, q Q2.

A key-hole, 7c, of ordinary shape, is cut in the drum 2 opposite the endof the shaft D, and is extended in the form of a narrow slot, it,through a rotary box, 13', which is swiveled in the end bracket of theframe q q. The openin g k in the bracket itself is of the same shape asthe key-hole k, its circular portion being occupied by a cylindricalwrist, uniting two circular disks, which complete the rotary box, asshown in Figs. 5 and 9. The above devices accommodate. a simple key, K,Fig. 10, hav- This motion is indicated 1r 0 abrack'euso' as to pre xB'is extended in- "it D, so as-to pre- ..e of skeleton keys.

also 'to carry a series of p T, which are engaged by the .-pawl-springor click, 8 the same mg to insure turning the key forward in 7 ,.reproper direction, and to prevent turning -the key backward to thekey-hole, and also a to give audible notice of the approach of thetrip-handrto zero. Where this last effect is not considered important,acontinuous ratchetrim may be formed on the box B. When the key iswithdrawn the spring 8 remains in mesh with the ratchet, as shown inFig. 10, and holds the box in position.

The bit of the key K terminates in a small projection, k parallel to theshank. Matching this is a single hole, h, in a broad circular flange, m,at the outer end of a sliding sleeve,

. E, which-is mounted on the outer end of the shaft D. Another sleeve, Eis arranged within the sleeve E, and clamped in position by means of asetscrew, l and the sleeve E is caused to rotate therewith by means of aspline and spline equivalents, 'j. either or all of which may be used. jis a spline-extension, working in a notch in a flange, i,- on the sleeveE and j is a pin inserted into :the latter through a stop-slot in thesleeve E Between the flange 'i and that of the sleeve E a spiral spring,a", is arranged to press said sleeve outward. I

Vhen the key K is introduced to turn the trip-hand it forces back thesleeve E, as indicated by dotted lines in .Fig. 9, before it can enterthrough the ward formed by the bracket g. It can now be turned in thedirection of the arrows 8, Figs. 7 andfi, and when the projection kcomes opposite the hole It the sleeve E is projected by the spring 8 andthe key is coupled to the shaft D. The trip-hand can now be moved backand forth at will by means of the key; but the key cannot be disengagedfrom the sleeve until the hole h is again in line with the key-hole,.asshown in Figs. 5, 9, and it can only be brought to this position aftercarrying the trip-hand to zero in the direction of the arrows 8.

As thus moved the trip-hand is stopped at I zero by thecontact of astop-spring, s, with a steel-faced shoulder in a volute stop flange orcollar, 0, at the inner end of the sleeve E, which is shown in Fig. 12.The spring 5 is supported parallel to the shaft D, or nearly so, bymeans of the supplemental frame g, which supports the shaft, and beingheld at both ends, as shown, it cannot be sprung out of place. It isprotected against undue strains,

however, by the ratchet device 1" 8", as before described.

When the trip-hand is turned forward by registrations to and beyondzero, the zeroguard c .9 offers no obstruction; but when the trip-handis turned back said zero-guard forms 209.728 BESTAVAlLABLE cop stop, asbef re stated; the thehand is at zero the'ro ation of the key in eitherdirection is prevented by the zero-guard on one side and the ratchetdevice 1' s of the keyguard on. theother. The key must then bewithdrawn. i l

The ratchet device 1* s serves also, in connection with. the insertedkey and the keyclutch-E h, to lock the'trip-hand against motion with theshaft A, and thus insures the detection of any. attempt to accomplishany manipulation of the trip-hand by leaving the key in its box B or toescape detection in this manner after finding that the hand can only beleft at zero. The ratchet device limits the complete rotation of the keyto thedirection of the arrows 8,'whilethe movement of the shaft A wouldtend to turn it in the direction of the arrows 9. l

- If preferred, a key with a round shank can be used, its bit, incombination with the inward extensions of the box 13, serving to rotatethe latter; and with a flat shank the lateral bit may be omitted, ifdesired. I

As another modification, we propose constructing the key-bit with anotch, k", or a shoulder, W, in line with the projection is, as shown inFig. 10, the same to be occupied by a corresponding ward, supportedparallel to the bracket q, or its equivalent. The object of thisconstruction is to provide a guide which will steady the described formof flat key, and also serve to prevent the escape of the projection 1&from the socket h of the key-clutch before the rotation of the key-boxis completed. The said socket h of the key-clutch may also be adepression or notch instead of an orifice.

We alsopropose to operate the main slide S by means of a bell-cranklever, S, as illustrated in Fig. 3*, so as to provide for pullingdownward on the operating strap or its equivlent.

To facilitate comparing this specification with that of our said PatentNo. 190,021, like letters of reference have been used for the respectiveparts and their substitutes as far as possible. v

Nothing that-is shown in said Patent No. 190,021 is intended to beclaimed as a part of the present invention.

The following is what we ,now claim as new and desire to securebyLetters Patent, namely:

1. A rotary key-box, B swiveled substantially as herein described, andprovided with a ratchet device, '1' 8 in combination with a zero-guard as, for the purpose set forth.
